Use long division to convert 2/9 to a decimal. Your approximation should have one decimal place simplifed

1 answer

To convert 29 to a decimal using long division, we can follow these steps:

  1. Set up the long division of 2 by 9. Since 2 is less than 9, we start by adding a decimal point and zeros (making it 2.000...).

  2. Divide 2.0 by 9. Since 9 can’t go into 2, we look at 20 (after putting a decimal point):

    • 9 goes into 20 two times (because 9×2=18).
    • Write 2 above the line.
  3. Subtract 18 from 20: 2018=2

  4. Bring down the next 0 (to make it 20 again):

    • Again, 9 goes into 20 two times (another 9×2=18).
    • Write another 2 above the line.
  5. Subtract 18 from 20 again: 2018=2

  6. This process will repeat indefinitely, yielding the digits 222..., which goes on forever.

Thus, 29=0.222...

To simplify 0.222... to one decimal place, we round it. Since the second decimal place (2) is less than 5, we round down.

Therefore, the value of 29 rounded to one decimal place is: 0.2
